Indicator C3 — Duplicate or Near-Duplicate Projects

AI-verified / Na-verify ng AI Data as of October 21, 2026

Duplicate or Near-Duplicate Projects

Very similar descriptions within ~100m or identical coordinates across contracts/years.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: contracts 24HF0004 and 23HF0014 have near-identical descriptions about 1947 m apart (funding years 2023, 2024; ₱96.20M, ₱66.95M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or extension of the first project, but this is not labeled in the titles.

The two contracts have identical titles with no distinguishing markers, are in the same barangay and sitio, and are about 2 km apart. Both are for 'Construction of Flood Mitigation Structure at Combado River, Sitio Combado, Barangay Cantuod, Balamban, Cebu', funded in consecutive years, and by the same contractor. There is no evidence in the packet that these are different works (e.g., no phase/segment/section markers or different locations in the title). The evidence is complete and checkable.
